Calvin Tucker, a GOP delegate and member of the Pennsylvania Republican Party, was scheduled to introduce the candidate. At the end of the meeting, he thanked Trump "for being brave enough to come" to North Philadelphia.

Renee Amoore, a local business leader, said Trump has support in the community, despite polls showing otherwise. "Pennsylvania has your back, and Philly in particular," she said, and thanked him for "coming to the 'hood."

Trump's visit is a move to reverse cavernously unpopular support among minorities, including the black community.

Trump's base has long been white men, but he's recently talked about making the GOP the 'home of the African-American voter." At his rallies, he often asks of black communities "what the hell do you have to lose" by voting for him.

A recent NBC News/Survey Monkey poll found just 8 percent of African Americans would vote for Trump. His opponent, Hillary Clinton, has support of 87 percent of the black community, according to the survey.

Lambert was eventually hit over the head with the sign. The Bucks County resident asked for charges to be filed, but police declined to make an arrest, saying the shoving match didn't warrant legal action.

Lambert came back a short time later holding up a new handwritten poster that read, "I love walls."

Following the roundtable, Trump met with the family of Iofemi Hightower, a young woman who was murdered execution-style along with two others outside a Newark, New Jersey, school in 2007. According to the New York Times, prosecutors said the 20-year-old was brutally slashed with a machete.

The murders were linked to a violent gang and the men accused were in the country illegally, the girl's mother said.

"While pushing a hateful, divisive and dangerous agenda, his photo-op in Philadelphia today is nothing more than an offensive gimmick," Dukes said in a statement. "Donald Trump is extremely out of touch with the African-American community."

In a one-on-one interview with NBC10's Lauren Mayk, Trump said Democratic leaders have given the African-American community "nothing."

"The guns on the street, they have to take them away from criminals, they know who they are. You have criminals who are carrying guns and beyond guns...they're carrying bombs," Trump said.

He said the department needs to use stop-and-frisk, a controversial surveillance technique where officers search people without reasonable cause. Opponents say the practice is nothing more than profiling and has led to unjust arrests and shooting deaths.
